| 摘 要： | 美澳通过HIFiRE项目在高超声速飞行器的气动、推进和控制等领域进行了深入探索，并对一体化设计有动力飞行器的高速性能进行了评估。以单项验证、步步推进的系列飞行试验方式，对乘波体布局以及不同动力方式开展原理研究，结合飞行试验对设计状态进行验证，取得一系列有价值的飞行数据和阶段性成果。通过梳理气动/推进一体化过程中相关飞行试验，提炼出总体设计中的关键技术和试验结论，并对有动力飞行器的发展趋势作了分析。研究显示发生转捩的单位雷诺数范围在3×106~4×106之间，适应小迎角高升力特点的乘波体与超燃冲压发动机的组合成为优选方案，所取得的成果为带超燃冲压发动机高速飞行器总体方案设计提供了一定的参考。

| Abstract: | By the HIFiRE project, America and Australia have deeply investigated the aerodynamics, propulsion and controlling system of hypersonic aircrafts. The high-speed ability is evaluated for the integrated design of aircrafts with propulsion system. A series of valuable flight-data and staged achievements are obtained by the flight tests of single-target evaluation and step-by-step improvement, the principal study of waverider shapes and different propulsion systems, and the verification of designing condition by flight tests. The key technique and experimental conclusion are summarized for the overall design by organizing the flight tests of dynamics/propulsion integrated processes. Moreover, the developing trend is analyzed for the aircraft with propulsion system. The results show that the unit Reynolds number of the transition is between 3×106 and 4×106, and a combination of scramjet and waverider with high lift characteristics at small attack angle is the optimized design, which gives some suggestions for the overall design of high-speed aircrafts with scramjet. |
